You say you want a revolution? Logitech today launched its MX Revolution and VX Revolution wireless mice. Both models feature hyper-fast scrolling with a revolutionary alloy wheel - the MicroGear Precision Scroll Wheel - that spins freely for up to seven seconds, spanning hundreds of pages with a single flick of the finger and setting a new benchmark in scrolling efficiency.

The Logitech MX Revolution mouse includes an intelligent twist to the MicroGear Precision Scroll Wheel: The motorized wheel automatically switches between free-spin mode and click-to-click mode, with Logitech's SmartShift technology, based on the best setting for the application being used. In some applications, such as Microsoft Excel, Logitech's technology also senses the speed at which people spin the wheel - if spun rapidly, the wheel goes into free-spin mode; if spun slowly, the wheel shifts into click-to-click mode. Users can also toggle manually between modes - by pushing down and clicking the wheel. And settings for the wheel and for all of the mouse's seven buttons can be customized for individual preferences within the included Logitech SetPoint software or with Logitech Control Center software for Mac, available via download.

The MX Revolution also features a second wheel near the thumb that can either be used to zoom in and out of photos and documents, or to quickly switch between applications, furthering navigational efficiency. The Logitech MX Revolution mouse has a suggested retail price of $99.99.

Designed for notebook users who want the very best in a mouse, the Logitech VX Revolution mouse balances portability and comfort. It's smaller in size than the MX Revolution mouse and includes a slot to store the 2.4 GHz micro-receiver, making it more portable. And its ergonomic design, rubber-lined thumb grip and slightly concave key plates make it highly comfortable to use.

The base of the mouse features a switch that can shift the MicroGear Precision Scroll Wheel from free-spin mode to click-to-click mode. The mouse also includes a zoom slider that makes it easy to zoom in and out of open documents and photos. The Logitech VX Revolution mouse has a suggested retail price of $79.99.
